Problems solved by technology

Even for some small jobs, such as a single photograph, the translation or conversion into the printer-readable format can result in delays of several minutes as the data are transmitted and ripped.

Embodiment Construction

[0018]To address the issues related to prior art methods of requesting a print job as described above, the present disclosure relates to caching by a print driver in printer-readable format of documents, e.g., rasterized renditions of popular, lengthy or important documents in order to avoid the cost or time associated with re-rasterization with each re-printing.

[0019]Referring to FIG. 1, there is illustrated a system 100 according to the present disclosure that includes a workstation 110 that has a processor or processing unit 112. The system 100 further includes at least one print driver 120a and may include additional print drivers such as print driver 120b, wherein the workstation 110 and the at least one print driver 120a and any additional print drivers such as print driver 120b are configured for interfacing via a network 10. The processing unit 112 of the workstation 110 has a set of programmable instructions, e.g., software, configured for implementing a print job request f...

Abstract

A system for prioritizing a cache of print jobs associated with at least one print driver includes a workstation having a processing unit and at least one print driver having a processing unit, that interface via a network. The workstation implements a print job request for a document and determines whether a document key identifier associated with the document exists. If not, a key is created. If a printer-readable format for a document associated with the key identifier is stored in or is pre-existing in one of at least two caches, the print driver assigns a prioritization identifier to the format. The system retrieves the printer-readable format from the cache to produce a print job output. Since the cache stores the document in printer-readable format, overall printing time is reduced. The format may be moved from one cache to another depending upon priority. The corresponding method is also disclosed.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to systems and methods for printing and converting documents from a workstation to a print driver.[0003]2. Description of Related Art[0004]In current printing environments, frequently printed and popular documents (e.g. memos, e-mails, manuals, corporate logos, business cards, photographs, letterhead, etc) must be completely reprocessed each time they are printed. The user selects the document(s) to be printed from a workstation, and then transmits the document(s) to a print driver over a network. The print driver translates or converts the data from a language in a computer-readable format such as PostScript or Adobe PDF into a printer-readable format such as a binary language that the print driver understands (a computationally intensive process often referred to as “rasterizing” or “ripping”), and then generates the print job output from the printer-readable format. (As defined herein, the terminology “print d...
